Hello, Can you send me the amino acid sequence and the Uniprot or PDB file?
1 answer-
Historically, the molecular weight of BSA has been cited as 66,1201 or 66,2672. However, it was revised in 1990 to 66,4303. All three values are based on amino acid sequence information available at the time of publication. The complete sequence can be found in the UniProt

I make a mistake to put this BSA powder (A9647-100G) in the room temperature for 39 hours. Can it still work?
1 answer-
The long term storage recommendation for this product is refrigerated at 2-8 °C, but it is shipped at ambient temperature. Refrigerated products that ship at ambient temperature are stable for up to 2 weeks to allow for transit time. Items left at room temperature for short periods will not be adversely effected.

Would it be safe to use product A9418 if it was accidentally stored at -20°C for approximately 24 hours, even though it is intended to be stored at 2-8°C?
1 answer-
The performance of the item after storing it at -20°C cannot be guaranteed, and testing its functionality is recommended.

Can BSA ever contain alpha1 anti-trypsin as a contaminant?
1 answer-
The available Bovine Serum Albumin products are not tested for the presence of alpha-1 antitrypsin (AAT). AAT is typically found in Bovine Serum, however, it is unknown if the isolation and purification methods employed in the production of BSA would degrade this protein. A brief search of the literature shows AAT has a molecular weight range of 45 - 52 kDa. It is irreversibly degraded at pH levels below 5. A further review of the literature on potential removal or purification would be recommended.
